ENDLESS-FILM REEL.

T0 all whom it concern: Be it known that'I, SAUL PONON a c1t1- zen of the United States, and a resident of Newark, in the county of Essexand State of New Jersey, have invented certain new I and Useful Improvements in Endless-Film Reels, of which the following is a specification.

This invention relates toan endless film reel. The organization of the invention comprises a reel, by means-of which a" film is simultaneously wound up and unwound on said reel.

In the accompanying drawings Figure 1 is an elevation of an exemplification of the improved reel with a film and Fig. 2 represents a top plan view of Flg. 1.

A supporting block 20 has extending therefrom a guide rod 21, with the collar 22. A stanchion 23 alsoextends from the block 20.- A pulley 24 with the belt 25 is journaled on the rod 21 and has secured thereto the disk 26.

A cone shaped guide block 28 with the small end 29 and the large end 30 is journaled on the rod 21. A spring 32 bears between the collar 22 and the end 30 of the guide block 28. A guide cover 35 having formed therewith the lugs 36 is supported on the stanchions 23. A moving picture film is indicated by 40 and is shown unwinding from its central portion and simultaneously being wound up at its outer portion. The said film encircles the cone shaped supporting block 28, bears on the disk 26 and is guided by the cover 35.

To operate the device the belt 25 is continuously turned by any suitable means not shown, and by which the disk 26 and the film 40 is turned. The film 40 leaves the block 28 and is actuated by the projecting machine or other device in which it is used (not shown) and after passing through the said machine returns to the reel. The film is an endless one and winds up and unwinds on the same guide block. Thereby one of the usual reels is eliminated. The conical wall of the guide block 28 guides and allows the easy discharge of the film at its core and carries it over the other portion of the film Specification of Letters Patent Patented Jan. 22, 1218.

that is supported on the disk 26, and should the film become unduly strained the block 28 will rise against the tension of the spring 32. a

When the, disk 26, turns, the sprocket Wheel ofi a motion picture machine not shown also turns, and the said sprocket wheel engaging the film 40 pulls the latter at its core from the disk 26. The cone shaped guide block 28 guides the film 4.0 as it is discharged from the reel. After passing over the sprocket wheel the film 40 returns to the disk assisted by the rotations of the latter. As the film is an endless band it is continuously unwound from its center or core and wound up on the outside.

Having described my invention what I desire to secure by Letters Patent and claim 1s:

1. In a reel of the character described the combination of a supporting rod, a pulley journaled on the rod, a disk secured to the pulley, a guide block for a film journaled on the rod with one end normally. bearing against the face of the disk and a flexible medium bearing against the other end of said block.

2. In a reel of the character described the combination of a supporting rod, a pulley journaled on the, rod, a'-d1sk carried by the pulley, means to turn the pulley, a cone shaped guide block for a film journaled on the rod with one end normally bearing against the face of the disk and a ring bearing against the other end of said lock.

3. In a reel of the character described the combination of a supportin block, a guide rod extending from said look, a pulley journaled on the said rod, a disk supported by said pulley, a cone shaped guide block for a film journaled on said rod and normally bearing on said disk, a spring bearing on the guide block, stanchions extending from the supporting block, a guide cover for said film supported on said stanchion and means to turn the pulley and disk and thereby continuously move the film permitting it to be discharged at its core and combination of a rotating disk, a rotating Signed at the borough of Manhattan, in cone shaped'guide block over the disk for an the county of New York and State of New endless film, a stationary cover for the film York, this 22nd day of May, A. D. 1916.

and means to turn the disk and thereby dis SAULPONON. 5 charge the film from its core and permit the Witnesses:
